Experience

Primary effects

  • Increases alertness and reduces fatigue, leading to a strong stimulating effect.
  • Induces significant body warmth and pupil dilation.
  • Suppresses appetite completely, with a notable absence of hunger for prolonged periods.

Peak character

  • Characterized by a heady, charged, and slightly dreamy feeling.
  • Leads to intense euphoria, described as being on 'cloud nine' or 'ecstasy'.
  • Can cause an extraordinarily intense libido, potentially leading to prolonged sexual activity.

Negatives / side effects

  • Highly moreish; there is a strong urge to redose and binge, indicating high addictive potential.
  • Taking too high a dose can lead to a 'zombified' but enjoyable state, suggesting impaired function.
  • Risk of long-term disappointment in normal activities due to enhanced pleasure from the drug, potentially damaging the brain's ability to produce natural pleasure chemicals.

Aftereffects / comedown

  • Can lead to a brutal crash after the high, replaced by bottomless depression and hopelessness.
  • After-effects include feeling drained, wired, and a background headache, making one feel 'rough'.
  • The hangover can persist for a lengthy period, potentially for a week, causing demotivation and a strained mental state.

Reagent testing

Expected reactions
MarquisOrange → brown/black
MandelinGreen → black
Simon'sBlue (secondary amine — key distinguisher from amphetamine)
LiebermannOrange → brown

Adulterant detection: Simon's test blue confirms secondary amine (methamphetamine vs amphetamine). Fentanyl present in some supply chains, especially pressed pills.

Simon's test is the key differentiator from amphetamine. Fentanyl strip recommended for pressed/pill form.
